For some reason Microsoft decided not to enable that function in some editions of RTM in SQL server 2008 (annoying but meh). So looking around I found Microsoft Connect article, link. According to that it was suppose to be for the IA64 only but I was only running developer edition on x86 Windows XP Sp3…
What made it more annoying was you don’t get any error messages or nothing indicating it is not going to work. But I was able to use the wizard to create the maintenance plan; heh guess they over looked that.
So anyhow I decided to install CU4 and I got my Maintenance Plans back again…
CU4 download link; note you have to specially request it.
